Confined spaces with poor ventilation trap dangerous gases and particulate matter in the atmosphere, exposing workers to potential respiratory infection, illness or even death.
If the area is known to be hazardous, workers must use a forced air blower to replace the air and reduce the risk of asphyxiation. However, many safety managers and cleaning crews struggle to properly ventilate spaces by failing to calculate the air exchange rate per cubic foot.No two confined spaces are exactly alike. Some don’t have enough ventilation to create a safe atmosphere, while others have none, making them unfit for prolonged human occupation. Variations in
